To all whom it may concern:

Be it known that I, EDWARD F. HALLOOK, a citizen of the United States, residing in the boron h of Brooklyn, county of Kings, city and State of New York, have invented an Improvement in Sales Packages, of which the following is a specification.

This invention relates to a sales package and more particularly to a sales package adapted to contain grease or oil or a similar substance and is so constructed that in the use of the same the contents are entirely dispensed therefrom. The sales package made in accordance with this invention, for example, is particularly adapted for use as a grease gun. Much difiiculty has heretofore been experienced in the use of grease guns as ordinarily constructed because of the inaccessibility of the parts to which the grease is to be applied; for example, gear cases and differentials of motor vehicles, and the fact that in the ordinary form of grease guns a lar e proportion of the grease is forced by t e piston and not from the gun. It will be understood, however, that while may improved sales package, is particularly a apte for use as a grease gun, its uses are not so limited.

The object of the invention is to overcome these difiiculties and to provide a sales pack age of relatively inexpensive construction, convenient for use, and which may be fully emptied, one that is not refillable, and which is leakproof. In carrying out the invention,

I preferably employ a cylindrical body member of flexible fabric or any other suitable material treated in such a manner as to be impervious to the grease or oil' or other contents of the package and fitted at one end with a spout or nozzle member through which the contents of the package may be forced, and provided at the other end, or in a position oppositely disposed to the discharge nozzle, with means for twisting the body member to collapse the same and thereby create a pressure therein which forces the contents of the package from the nozzle to the place to which the contents are to be applied. It will be understood of course as the body of the package is flexible, it may be used in places which are inaccessible to the rigid bodies of ordinary grease guns,

and that due to the flexibility of the body of the package the same may be forced into the nozzle to completely discharge the contents of the'package. Other advantages of my improved sales package will be equally obvious.

In thedrawing:

Fig. 1 is an elevation showing one form of my improved sales package.

F ig; 2 is an elevation and partial central longitudinal cross section of the same.

Fig. 3 is a view similar to Fig. 2, showing another form of the invention, and

F ig. 4 is also a view similar to Fig. 2 showing still another form of the invention.

Referring to the drawing, and particularly to that form of the invention shown in Figs. 1 and 2, the sales package made in accordance with my invention preferably comprises a body member 10 which is cylindrical, as illustrated, and may be made of any suitable flexible fabric, such for example cotton duck, and is so treated as to be impervious to the material whichit is to contain. For example, it may be impregnated with bichromated gelatinous matter including a sufficient quantity of zglycerine to maintain the pliability or flexibility of the body member, or with a suitable rubber or gum product, or by being subjected to a suitable oxidized oil treatment, depending, as will be apparent, upon the nature of the material which is to be placed in the package.- As illustrated in the drawing, this body member is shown as cylindrical, and while this is the preferable form, it may be made in' other configurations without departing from the nature and spirit of the invention. In this, as in other forms of the invention, the body member or casing is non-extensible, but is flexible and made impervious to the contents thereof. As illustrated, one end of the cylindrical body member 10 is suitably made of smaller diameter to fit over and be secured to a suitable spout member. This spout member preferably comprises a nozzle 12 and a flaring end 13 over which latter the reduced end of the body member 11 is fitted and suitably secured to make a tight joint. Interiorly at the .spout member or discharge end the package is provided with a seal 15 which is made of any suitable material and connected to the periphery of the flared end of the spout member or otherwise in any desired manner, it being understood that this seal member is also made. impervious to the contents of the package and is constructed in such a way as to be disrupted by the pressure exerted on the contents of the package and.

conveyed thereto so as to permit the con tents of the package to be discharged through the spout member.

At the the same is preferably reduced in cross section as indicated at 16 and provided with a collapsing ring 17 and then extended agam in a flattened section as indicated at 18 which is closed or sealed by suitable strips of metal 19 or other material or otherwise, the parts of which enclose the flattened end 18 of the body member and are connected by rivets 20 or otherwise with the flattened part of the end of the body member intervening so as to make end of the package. Furthermore, the strips 19 may be fitted with a ring or other grip 21 so as to facilitate the emptying of the package in the use thereof.

Now as will be apparent, the package, as hereinbefore described, may contain grease or oil or any other similar material, and in the use thereof the spout member or discharge end of the package is held in one hand with the nozzle placed in the receptacle into which the contents of the package are to be discharged and'the opposite end of the package twisted by grasping the ring or other part of the opposite end of the package in the other hand and twisting the same, the twisting operation causing the package to gradually collapse from the twisting end, thereby first creating a pressure within the package which is imparted to the contents thereof and transmitted thereby to the spout seal to break or rupture the same, and by the continued twisting of the end of the package the entire contents thereof may be discharged through the spout end, the entire contents being discharged by the possiblllty of forcing the collapsed body of the package into the flaring end of the spout member.

By reference to Fig. 3, it will be seen that in carrying out the invention, the body member of the package may be made of ordinary untreated flexible or collapsible but non-extensible fabric indicated at 22 and adapted to contain a suitable cartridge for the grease or other material. In this construction, the body member 22 is contracted at one end as indicated at 23 to fit over the flaring end 24 of a spout member, the nozzle of which is indicated at 25. At the opposite end the construction of the body member is similar to that described in connection with the form of the invention shown in Figs. 1 and 2; that is to say, the opposite end is provided with a reduced section of a collapsing ring 26 and with a flattened extremity fitted with suitable strips 27 to make a tight joint and a twisting ring 28. In this body member a cartridge containing the grease or oil is placed, and as shown in Fig. 3, this cartridge 29 is preferably conopposite end of the body member,

a tight joint at this tents. The cartridge 29, as illustrated,- is

preferably closed at one end as indicated at 30. The other end of the cartridgeis open and is fitted with a cap having a conical portion 31 open centrally. The cap also includes a flange 32 to which the open end of the cartridge is secured and by which, in any suitable manner, the position of the cartridge is determined in the outer casing of the package. The opening in the cap 31 is normally closed by a seal 33, which, in the use of the package, is disrupted in the same manner as hereinbefore described in connection with the seal 15 in the form of the invention shown in Figs. 1 and 2.

Referring to Fig. 4, the invention may assume another form in which the body member comprises an exterior casing in the samemanner as that shown in Fig. 3, but in which, as hereinatfer described, the cartridge employed is made an integral part of or lining for the casing. In this structure, as in the other forms of the invention, one end of the casing 34 is of reduced crosssection and adapted to'fit over and be secured to the flaring member 36 of a suitable spout, the nozzle of which is indicated at 37. Also similar to the other forms of the invention, the other end, of the casing and cartridge lining are reduced and fitted with a collapsing ring 38 on the opposite side of which they are extended and flattened and provided with suitable bands 39 to make a tight oint, the bands 39 being provided with a twisting ring 40. The cartridge employed in this form of the invention is indicated at 41 and is madelof suitably treated paper or any other material made impervious to the grease, oil or other substance which it is to contain. The closed end of the cartridge is indicated at 42. The opposite open end of the cartridge as indicated at 43 is of reduced cross section and preferably rounded and open at its extremity, the opening being normally closed by a disruptable seal 44 also made of suitable material which is treated in any desired way so as to make the same impervious to the contents of the cartridge. In this construction, the cartridge is made extensible under pressure by being provided with series of longitudinal ribs or corrugations 45 which are normally contracted, but which extend under pressure to increase the diameter of the cartridge in order to prevent the cartridge from breaking or becoming rup- The forms of the invention as shown in Figs. 3 and 4-. are used in precisely the same manner as that described in connection with the form of the invention shown in Figs. 1 and 2 and as will be apparent, the nozzle members may be threaded exteriorly at their extremities as .indicated at 46 and provided with caps 47 to prevent the leakage of the contents of the package after the seals have been disrupted and the entire contents of the package have not been utilized at one time. It will also be obvious that while I have herein shown and described my improved sales package as adapted for use in containing and dispensing oil or grease and in a cylindrical form, it may be used for otherobvious purposes and made in any deslred configuration.
